CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 290,086, dated December11, 1883.

I Application filed March 1, 1888. (No model.)

To all whont it nuty concern:

Be it known that we,PHINEAs E. MERRIHEW, of Fairhaven, county ofPlymouth, and MEL- VILLE (J. POLAND and EDWARD F. POLAND,

both of Boston, in the county of Suffolk and State of Massachusetts,have invented certain Improvements in Oar-Couplings, of which thefollowing is a specification.

This invention has for its object to provide 10 the draw-head of acar-coupling with an attachment adapted to hold up the coupling-pinuntil the entrance of the link into the drawhead, and then allow the pinto drop into the link; and also adapted to enable the inclination of acoupling link from the draw-head,to which it is secured by thecoupling-pin, to be varied by moving the pin upwardly or downwardly inthe draw-head, so that the link can be guided to enter a higher or lowerdraw-head on another car, without the necessity of the attendantstanding between the cars to guide the link, the pin being provided withmeans whereby a person standing at one side or at the top of the car canraise or lower the pin,

and thus vary the inclination of thelink.

Our invention consists in the improved attachment, which we will nowproceed to describe and claim.

Of the accompanying drawings, forming a part of this specification,Figure 1 represents a longitudinal vertical section of a drawheadprovided with our improvement before the link is introduced. Fig. 2represents a similar section, showing the link introduced 3 5 into thedraw-head.

The same letters of reference indicate the same parts in all thefigures.

In the drawings, a represents a draw-head having a contracted mouth forthe reception 0 of the link I), and an internal cavity or'chamberextending above and below said mouth,so that the link can be inclinedeither'upwardly or downwardly from the draw-head.

0 represents our improved attachment, which 5 is composed of a leverhaving arms 2 3, and

pivoted at 4 to the lower portion of the drawhead. When the link is outof the draw-head, the arm 2 of the lever rests by its own weight againstthe lower side of the mouth of the draw the pin,when raised,will permitthe link to tip head and supports the coupling-pin 1) in a raisedposition, as shown in Fig. 1, the arm 2 at the same time projectingforward under the hole into which the pin falls. Vhen thelink enters thedraw-head, it strikes the arm 2, and turning the leverc on its pivotforces the arm 2 backwardly from under the pin 1), thus allowing thelatter to drop through the link,and forces the arm 3 upwardly, so thatit will bear against the lower end of the pin, as shown in Fig. 2. Thelink being fulcrumedon the contracted mouth of the draw-head, nowpresses upwardly at its inner end against the inclined forward edge ofthe arm 2, the upper end of said arm projecting somewhat over the end ofthe link, so that the latter, by its pressure against the arm 2, pressesthe arm 3 upwardly against the lower end of the coupling-pin, and isheld down at its inner end by the arm 2, and prevented from tippingupwardly, excepting as permitted by said arm. The couplingpin is pivotedat its upper end to a rod, h, which is adapted to be moved up or down toraise or depress the pin by-any suitable means for example, by beingextended to the top of the car, (if a freight-car,) and thereprovidedwith ahandle adapted to be grasped by abrakeman on the roof of the car,or at any point above the draw-head, or by being pivoted to an arm, 2',on a horizontal rock shaft, j, journaled in bearings on the end of thecar, and adapted to be operated from one or both sides of the car.

It will be seen that when the link is in place in the draw-head and isfree at its other end,

5 upwardly at its inner end and turn the lever c on its pivot as far asthe upward movement .of the pin will permit, thus giving the link anydesired downward inclination from the draw-head. When the-pin is pusheddownwardly,it will turn the lever c on its pivot and cause the arm 2 todepress the inner end'o'f the link, and thus give the latter any desiredupward inclination from the draw-head, as shown in dotted lines in Fig.2. All necessity of 5 going between the cars when they are being coupledis thus avoided.

We clairn 1. The combination, with the draw-head having a contractedmouth and an internal chamber, formed as described, of the pivoted lever0, having arm 2,adapted,when the lever is in its normal position, tosupport the coupling-pinin an elevated position,to be displaced by theentrance of the link into the draw-head, and thereafter to support theinner end of the link, and the arm 3, adapted,when the leveris displacedfrom its normal position, to be pressed by the weight of the linkupwardly against the lower end of the coupling-pin, whereby when the pinis adjusted vertically the arm 2 will be correspondingly adjusted andcaused to vary the inclination of the link, as set forth.

2. The combination of the draw-head, the pivoted lever 0, having the arm2, adapted to support the inner end of the link, and the arm 3, adaptedto be pressed by the weight of the 20 link upwardly against the lowerend of the coupling-pin, and operating devices, substantially asdescribed, whereby an attendant at the side or top of the car is enabledto vary the inclination of the link by moving the pin 25 vertically, asset forth.

In testimony whereof we have signed our names to this specification, inthe presence of two subscribing witnesses, this 20th day of February,1883.
